Description

Technical Field

[0001] The invention relates to the technical field of brewing process optimization, and in particular to a method for designing a brewing formula of tangerine red wine based on a dynamic optimization algorithm. Background Art

[0002] In the brewing process of fermented wines such as Huajuhong wine, the differences in raw material ingredients, changes in the brewing environment, and the complexity of fermentation conditions all have an important impact on the quality of the finished product. Traditional brewing methods mostly rely on the experience of the winemaker, combining sensory judgment and some physical and chemical tests to determine the brewing conditions. Although this method has accumulated certain experience in practice, due to the complexity of the process and the diversity of brewing factors, it is difficult to achieve high-precision and stable control by relying solely on experience. Therefore, the traditional brewing process has shortcomings in dealing with the consistency and standardization of the quality of different batches of wines. Especially in the face of the market demand for high-quality, stable-tasting Huajuhong wine, the limitations of the existing process become particularly obvious.

[0003] In order to solve these problems, some studies and processes in recent years have tried to introduce mathematical models and computer control technology into the brewing process. For example, quality control technology based on multidimensional data analysis and applied statistical methods have achieved certain results in some brewing links. These methods monitor brewing environmental parameters such as temperature, humidity, pH value, etc. during the fermentation process, analyze the dynamic changes of the fermentation process, and try to establish a simple quality prediction model based on this. However, since most traditional methods remain at the level of simple correlation analysis and local optimization, they fail to achieve the coordinated optimization of multiple brewing stages and multiple parameters, making it difficult to effectively control the entire brewing process. In addition, with the gradual complexity of brewing technology and the improvement of wine quality requirements, the limitations of existing models have become more and more prominent, especially in the dynamic adjustment and adaptation of multi-objective optimization in different brewing stages, which has not yet achieved ideal results.

[0004] Traditional optimization methods such as genetic algorithms and particle swarm algorithms have been applied to the automatic control of some brewing processes to adjust a single or a few key parameters and optimize the objectives of a fixed stage. These methods have improved the brewing efficiency to some extent and have produced certain effects on the parameter control of a single stage. However, genetic algorithms and particle swarm algorithms have shown obvious shortcomings when facing the multi-stage dynamic, nonlinear and multi-objective optimization requirements of the brewing process. On the one hand, traditional genetic algorithms are difficult to cope with the rapidly changing requirements during the fermentation process and have limited parameter adaptability; on the other hand, particle swarm algorithms uniformly control parameters in different stages and fail to perform targeted optimization control for specific requirements such as sugar conversion in the early stage of fermentation, flavor generation in the middle stage, and texture balance in the later stage. The existing single algorithm is difficult to meet the multi-objective optimization requirements of multiple brewing stages, and lacks an intelligent and adaptive control mechanism to dynamically adjust brewing parameters.

[0005] In addition, in the field of brewing data analysis, the existing traceability analysis system also has certain shortcomings. Traceability analysis has been applied in the food, beverage and other industries, but in the brewing process of fermented wines, especially in brewing varieties such as orange red wine that have extremely high taste requirements, traditional traceability analysis systems can only record simple parameter fluctuations and lack effective tracking and analysis capabilities for subtle differences between different batches. In dealing with the uncertainty of multiple parameters and the brewing process, traditional traceability analysis is mostly limited to the backtracking of static data, and lacks real-time analysis and adaptive control capabilities for dynamically changing data during the fermentation process. This has led to the traceability analysis system failing to effectively discover the key parameters that affect product consistency, and failing to establish a multi-dimensional, multi-level data association analysis model in the brewing process.

[0006] As the demand for Huajuhong wine in the market gradually increases, consumers' requirements for the consistency of its taste, flavor, sweet-sour ratio and texture are also increasing. Existing technologies have obvious defects in meeting these requirements: on the one hand, since traditional brewing relies on manual regulation and experience accumulation, it is difficult to meet the consistency requirements of multiple batches of products; on the other hand, the existing automated control methods are not adaptable enough in complex fermentation processes, especially when facing the needs of collaborative optimization of multiple brewing stages and multiple parameters, traditional optimization algorithms lack pertinence. At the same time, since the brewing process of Huajuhong wine is affected by differences in raw material ingredients, environmental changes and fluctuations in fermentation parameters, the existing traceability system has limited ability to conduct in-depth analysis of brewing data and establish key parameter associations, and has failed to effectively solve the problems of taste stability and product consistency.

[0007] Therefore, how to provide a method for designing a formula for brewing tangerine red wine based on a dynamic optimization algorithm is an urgent problem that technicians in this field need to solve. Summary of the invention

[0008] One purpose of the present invention is to propose a method for designing a formula for brewing jujube red wine based on a dynamic optimization algorithm. The present invention combines a fuzzy adaptive collaborative evolution algorithm, an improved particle swarm optimization algorithm, and a traceability analysis system to achieve multi-stage intelligent optimization control of the jujube red wine brewing process. By dynamically adjusting key parameters such as temperature, humidity, and pH value at each stage, the sugar conversion rate, flavor formation, and texture balance are effectively optimized, so that the product meets high standards in terms of flavor consistency and quality stability. At the same time, the traceability analysis system tracks changes in brewing data in real time, providing scientific support for adaptive feedback optimization of subsequent batches, thereby greatly improving production efficiency and significantly improving the quality consistency and controllability of different batches of products.

Especially in the early stage of brewing, the present invention improves the sugar conversion rate and promotes the formation of initial flavor; in the middle stage, it accurately controls the ratio of temperature, humidity and pH value to optimize flavor generation; in the later stage, it ensures the balanced output of wine texture and improves the consistency of finished product quality.

[0071] Secondly, the present invention introduces adaptive inertia weight control through an improved particle swarm optimization algorithm, which not only enhances the adaptability of the system in different stages of brewing, but also balances the weights of exploration and development, so that the system has stronger search capabilities and dynamic response capabilities in the parameter space. In terms of parameter variation, the adaptive variation distribution mechanism adjusts the variation range according to the brewing needs of each stage, adopts large-scale variation in the early stage to widely explore the parameter space, and gradually reduces the variation range in the middle and late stages to ensure fine adjustment, so that the entire brewing process can achieve efficient and stable optimization on the basis of ensuring quality.

This dynamic adaptive feedback mechanism not only improves the consistency and stability of the product, but also significantly reduces the risk of substandard quality and ensures high-quality output of the product. Through data recording and in-depth analysis of the entire process, the present invention also enhances the traceability of the production process, provides strong data support for subsequent formula optimization, and makes the formula design more scientific and stable.

[0117] S56. Introduce a feedback-driven multi-stage variation range optimization mechanism to dynamically adjust the variation range by real-time monitoring of changes in fitness values ​​and improvements in brewing quality.

[0123] S63. In the mid-term fermentation stage, the weights of temperature, humidity and pH are set to be dynamically adjustable, and the weights are adjusted in combination with feedback data. The adjustment of the weight coefficient follows the real-time change of the target contribution, and the target with higher fitness obtains a higher weight;

[0124] S64. Set texture and flavor balance as key goals for the late maturation stage, and set weights e based on the contribution values ​​of texture and balance in the fitness function. 3 and e 4 If the texture or flavor balance is close to the expected value, the weight of the parameter is reduced and the weight is allocated to other secondary parameters to be optimized:

[0137] Embodiment 1:

[0138] In order to verify the feasibility of the present invention in implementation, the present invention is applied to a winery with large temperature changes throughout the year. The orange red wine produced by the factory requires a mellow flavor, appropriate sour and sweet, balanced texture, and must meet certain physical and chemical indicators. However, in production, due to the differences in raw material ingredients in different batches, fluctuations in environmental humidity and temperature, and uncontrollable factors in the brewing process, the sour-sweet ratio of the wine is often unstable and the flavor is quite different. Especially in the summer when the temperature is high, the difficulty of temperature control in the brewing process increases, which further affects the sugar conversion rate and the final taste consistency.

[0139] To solve these problems, the present invention is applied in the brewing process of the Huajuhong winery, and the specific operating steps are as follows. First, in the data collection stage, the brewing environment is monitored by a real-time sensor network, and the Huajuhong raw material composition and fermentation environment data, including temperature, humidity, pH value and sugar content, are continuously recorded. The collected data is standardized and an initial multidimensional data set is established. Secondly, a fuzzy adaptive co-evolutionary algorithm is used to analyze the complex relationship between the brewing parameters through fuzzy logic control and co-evolutionary mechanism, and the optimized initial formula setting is generated to ensure the optimal setting value of sugar conversion rate, flavor generation and texture balance. Subsequently, the brewing process is divided into three stages: initial fermentation, mid-term fermentation and late maturation, and each stage has different control focuses. The initial stage focuses on sugar conversion rate and initial flavor formation, the mid-term focuses on fine control of temperature and humidity to enhance the flavor generation effect, and the late stage focuses on texture balance to ensure the consistency of the taste of the finished product.

[0140] In actual operation, an improved particle swarm optimization algorithm is applied to control brewing temperature, humidity and pH value in real time. Each parameter is independently controlled by the agent, which continuously adjusts the set value based on real-time feedback. In the early fermentation stage, the exploration weight of the particle swarm is increased to ensure sufficient sugar conversion. In the mid-fermentation stage, the agent adjusts the parameters according to the temperature, humidity and pH value feedback from the sensor, avoiding the influence of high temperature on flavor generation and achieving an ideal sour-sweet ratio.

[0141] To further verify the effectiveness of the present invention, the traceability analysis system was applied to brewing data from different batches. By analyzing the brewing parameters of each batch and the flavor characteristics of the finished product, the traceability system established a correlation model between key indicators such as sugar conversion rate, sweet-sour ratio and texture and brewing parameters. Under this feedback control, the flavor stability of the finished product was significantly improved, while reducing the cost and time of readjustment.

[0142] Table 1 Comparison of experimental data of traditional process and the method of the present invention in the process of brewing orange red wine

[0143]

[0144]

[0145] According to Table 1 above, we can clearly see the significant improvements in different brewing parameters of the method of the present invention, especially the improvement in sugar conversion rate, sweet-sour ratio, texture consistency index and brewing cycle under different seasonal conditions. First, in terms of sugar conversion rate, the conversion rates of the traditional process in summer and winter were 72.5% and 68.2% respectively, while after using the method of the present invention, the sugar conversion rate in summer was increased to 83.4%, and in winter it reached 80.6%, indicating that the optimized multi-stage dynamic control has achieved a significant improvement in conversion rate, especially in summer when the temperature fluctuates greatly, the effect is more obvious.

[0146] The sweet-sour ratio is an important parameter for measuring the flavor of citrus red wine. When using traditional technology, the sweet-sour ratio in summer and winter fluctuates between 1.75 and 1.6, respectively. The method of the present invention optimizes it to 1.5 and 1.45 respectively through refined control, and the fluctuation range is significantly reduced. This improvement in consistency shows that the improved particle swarm optimization algorithm and multi-objective dynamic weight adjustment mechanism have a good regulatory effect on flavor control.

[0147] Texture consistency is an important manifestation of the quality stability of Huajuhong wine. Under the traditional process, the texture consistency indexes in summer and winter were 6.3 and 6.1 respectively, while under the optimized control of the method of the present invention, they were increased to 8.7 and 8.9 respectively in summer and winter, showing better wine body balance and texture stability. This significant improvement reflects the control effect of the traceability analysis and adaptive feedback mechanism in the present invention in the multi-batch brewing process.

[0148] Finally, in terms of brewing cycle, the method of the present invention also shows good optimization effect. The brewing cycle of the traditional process is 50 days in summer and 45 days in winter, while the method of the present invention shortens the brewing cycle to 45 days and 40 days respectively. This improvement not only effectively improves production efficiency, but also significantly reduces production costs, reflecting the efficiency and application potential of the method of the present invention in industrial production.

[0149] The experimental data clearly show that the method of the present invention is superior to the traditional process in terms of sugar conversion rate, flavor control, texture consistency and production cycle, further verifying its practical value in achieving high-quality and standardized production of jujube red wine.

[0150] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
